Embodiment one
It please refers to shown in Fig. 1, the present invention proposes a kind of fiber feed system, including fiber drawing-in device 100 and cabinet
200.The fiber drawing-in device 100 is set in cabinet 200, by cabinet 200 can for fiber drawing-in device 100 provide protection with
Installation.Specifically, it is provided with the position that unreels of fibrous webs in cabinet 200, and is equipped with and 200 inside phase of cabinet on the outside of cabinet 200
The fiber duct 210 of connection.When feeding, fiber after fiber drawing-in device 100, is led from unreeling after position leaves into fiber
Pipe 210 is cut off under the guidance of fiber duct 210 into injection molding machine.
Specifically, shown in referring to figure 2., in embodiments of the present invention, which includes fiber chute
100a, the fiber chute 100a have an enter line side and an outgoing line side.And fiber chute 100a also has and at least balances each other
Belling side, this compresses chimb and sets gradually along the direction of enter line side to the outgoing line side of fiber chute 100a, and adjacent two compress
The direction of chimb is staggered, and fiber chute 100a's compresses chimb to compress fibre when fiber enters fiber chute 100a
Dimension, to change the feedstock direction of fiber.
It should be noted that under normal conditions, fiber is stored in the roll form before cutting.When feeding, fiber
Releasing coil, fiber advance on equipment line along feedstock direction.During fiber feeding, fiber is not with independent one
Root unreels, but the more forms for being sticked together into fibre bundle are unreeled.Currently, being mostly used during fiber unreels
Roll shaft is oriented to it.And roll shaft is due to its cylindrical setting, and when fibre bundle bypasses roll shaft, the fiber that is sticked together
It is difficult to disperse, so that fiber, in infiltration, still stick to each other is poor so as to cause the effect of impregnation of fiber.Compared to existing
For technology, by technical solution provided herein, fibre bundle when by the process of fiber chute 100a, walk by fiber
Coil holder 100a's compresses chimb and can push against fibre bundle, and changes the direction of routing of fiber.I.e. fibre bundle is after compressing chimb
It can transfer.At this point, fibre bundle will receive from the concentrated stress for compressing chimb in the turning point of fibre bundle.Due to fiber
Every fiber is different from the contact area and contact point that compress chimb in beam, therefore the concentrated stress that is subject to of every fiber also not phase
Together.In this way, every fiber in fibre bundle can generate different degrees of deformation.And the fiber in fibre bundle is due to deformation degree
Difference can gradually disperse.And since every fiber is by from the concentrated stress for compressing chimb, and around compressing chimb, because
This fiber can be along the extending direction dispersion for compressing chimb.Again because the diameter of single fiber is small, limited strength compresses if only relying on one
Chimb needs to compress chimb and applies biggish concentrated stress to fiber so that fiber dispersion.And concentrated stress is excessive, may cause
Being damaged for fiber, influences the yields of final products.Therefore, fiber chute 100a needs to include belling side of at least balancing each other, with
While dispersing fiber, protection fiber is injury-free.
As it can be seen that compared with existing fiber feeding manner, fiber drawing-in device 100 provided herein has in fibre
The advantages of dispersing fiber during dimension feeding, improve fiber effect of impregnation.
Please continue to refer to shown in Fig. 2, fiber chute 100a includes mounting plate 110 and compresses bar 120, wherein compressing bar
120 are set on mounting plate 110, and are formed with and compress chimb.Bar 120 will be compressed to be set on mounting plate 110, and by compressing bar
120 formation compress chimb, can be designed respectively for mounting plate 110 with bar 120 is compressed, so that fiber chute 100a can
Adapt to different application demands.Also, compressing position of the bar 120 on mounting plate 110 can be freely arranged, so that fiber cabling
Frame 100a when in use, obtains best use effect.It should be noted that in the other embodiments of the application, fiber cabling
Frame 100a can also design for integral type, and compressing chimb can be by the protrusion on fiber chute 100a according to scheduled circuit projection shape
At.
The present embodiment it is further proposed that, compress on bar 120 compress chimb along perpendicular to mounting plate 110 direction extend,
And more compress and are parallel to each other between chimb.During fiber feeding, fiber can compress chimb through excessive root, will compress chimb
It is set as extending along the direction perpendicular to mounting plate 110, can shorten as far as possible under the premise of meeting dispersion fiber and compress chimb
Length, to shorten the length for compressing bar 120.In this way, one can reduce the occupied space of fiber drawing-in device 100, in order to fibre
Tie up setting of the drawing-in device 100 in cabinet 200；Two, the cost of manufacture of fiber drawing-in device 100 can be reduced.And make more
It compresses chimb to be parallel to each other, then the stability of fiber movement in fiber feeding procedure can be improved, to drop low-fiber tension variation
Amplitude, to avoid tension spikes and lead to the situation of fibre damage.Certainly, it in the other embodiments of the application, compresses convex
The extending direction on side can also be arranged with mounting plate 110 in other angles, such as 45 °, 50 °, 55 °, 60 °, 75 °, 80 °, 85 °, and
Compressing chimb and compressing can also need not be set as being parallel to each other between chimb.
Preferably, in the present embodiment, compress bar 120 and be set as the square bar that section is square, and square bar along perpendicular to
The direction of mounting rack extends, and the seamed edge of square bar side then forms and compresses chimb.It is advantageous in that using square bar, square bar has four
Seamed edge, each seamed edge, which can be used as, compresses chimb.Four seamed edges of square bar are arranged in a ring, can satisfy to majority of case
Under demand is compressed to fiber.And square bar is rotated using the extending direction of square bar as axis, the direction of each seamed edge of square bar can be adjusted,
So as to adjust the direction for compressing chimb on fiber chute 100a, regulative mode is simple, it is easy to accomplish.Also, due to square bar
Section setting is square, so that the equal length between the adjacent belling side of balancing each other on same square bar.The benefit being arranged in this way
It is, when fiber compresses chimb by multiple on same square bar, equal length of the fiber between adjacent belling side of balancing each other,
It advantageously ensures that the stabilization of fiber inner tensions in fill process, so that the charging rate of fiber be kept to stablize, and protects fibre
Dimension.
Please continue to refer to shown in Fig. 2, which further includes induction pieces (not shown), the induction pieces
It is set to the outlet side of fiber chute 100a, to incude simultaneously feedback fibers tension.Correspondingly, compressing bar 120 includes adjusting
Bar 121,121 movable of adjusting rod are set on mounting plate 110, to the fiber tension fed back according to induction pieces, adjustment
Position on mounting plate 110.
It should be noted that in existing fiber feeding manner, other than fiber effect of impregnation difference, due also to lacking to fiber
The control of tension causes in fiber feeding procedure, and the tension of fiber is unstable.Consequence caused by fiber tension is unstable is fiber
Speed into mold is inconsistent.And the screw rod in mold is to result in fiber quilt in this way according to fixed intervals cut staple
The length of cutting is inconsistent, causes the distribution of lengths of cut-off fiber uneven.And fiber length distribution is uneven, then can lead
The uneven of product is caused, product quality is influenced.It, can basis by the technical solution of the application it is found that during fiber feeding
The fiber tension that induction pieces are detected and fed back adjusts position of the adjusting rod 121 on mounting plate 110, so as to adjust fiber feed
Tension in the process, so that the speed that fiber feed enters mold keeps stablizing.
In the present embodiment, adjusting rod 121 is connected with a driving device (not shown), the driving device again with sense
Part is answered to be electrically connected.The fiber tension that induction pieces are sensed can Real-time Feedback to driving device, be preset with fibre in driving device
The tension threshold of dimension, when the fiber tension of induction pieces feedback exceeds tension threshold, driving device can correspond to driving adjusting rod
121, to adjust position of the adjusting rod 121 on mounting plate 110, answered so as to adjust what fiber was subject to from the concentration for compressing chimb
Power, and then control fiber tension.In this way, just can guarantee the stability of fiber tension during fiber feeding, guarantee fine
The travel speed of dimension makes the more uniform of fiber length distribution, to improve the yields of product.
Specifically, a sliding slot 111, the length direction of the sliding slot 111 and the charging side of fiber are formed on mounting plate 110
To being staggered, adjusting rod 121 is slideable to be set in the sliding slot 111.It is appreciated that adjusting rod 121 passes through sliding slot 111 and installation
Plate 110 is slidably connected, and realizes moving in stepless way of the adjusting rod 121 on mounting plate 110 to a certain extent.So that adjusting
After bar 121 and induction pieces cooperation, it can be more accurately controlled the tension of fiber, to guarantee the steady of fiber tension in feeding procedure
It is qualitative.Also, adjusting rod 121 is slidably matched with mounting plate 110, and the stability that not only adjusting rod 121 moves is high, but also adjusting rod
121 movement is also easy to control.Furthermore it is set in sliding slot 111 since adjusting rod 121 is slideable, the movement of adjusting rod 121
Direction can be predicted with move distance, and the influence after movement to fiber tension is also convenient for calculating, so that easily operated personnel adjust
Fiber tension.
Preferably, sliding slot 111 extends along the vertical direction.The advantages of this arrangement are as follows, it is easier to it controls adjusting rod 121 and exists
Movement on mounting plate 110.Certainly, in the other embodiments of the application, sliding slot 111 can also extend along other directions, such as incline
Tiltedly extend.In the other embodiments of the application, the motion path of adjusting rod 121 may be alternatively provided as curve, alternatively, adjusting rod
121 are also rotatably set on mounting plate 110.
It should be noted that after obtaining the feedback of induction pieces, operator can also in the other embodiments of the application
The position of manual control adjusting rod 121, to adjust fiber tension.In general, adjusting adjusting rod 121 by artificial mode
Position when, after induction pieces feedback fibers tension, operator can be according to the position of fiber tension size and adjusting rod 121
(by taking adjusting rod 121 is slided along the sliding slot 111 extended vertically as an example, the position of the adjusting rod 121 is adjusting rod 121 compared to cunning
The height of slot 111) corresponding relationship, adjust adjusting rod 121 position.In this way, need to only be adjusted primary in fiber feeding procedure
The tension of the position of adjusting rod 121, fiber can be maintained within a certain range.It operates in this way, although the essence of fiber tension control
Degree slightly lacks, but more simply can be used for the certain pairs of relatively low productions of fiber length distribution uniformity requirement with energy conservation
In product.
Please continue to refer to shown in Fig. 2, it further includes fixed link 122 which, which compresses bar 120, which is set to peace
In loading board 110, and between adjusting rod 121 and induction pieces.By compressing chimb in fixed link 122, can increase to fibre
